The precompiled Crayfish binaries are done on Ubuntu 14.04 and with
the package changes in Ubuntu >= 15.10 the binaries do not work there.
I have filed a bug report to fix the problem:
https://github.com/lutraconsulting/qgis-crayfish-plugin/issues/187

In the meanwhile you should be able to compile the support library
yourself, see the instructions:
https://github.com/lutraconsulting/qgis-crayfish-plugin/blob/master/README.md

[QGIS-it-user] PDF exports on OSX always convert text to outlines - Bug report #3975

[suburbanstudio]

Salve a tutti...
sto esportando un testo per una cartina e vorrei poterlo rifinire in 
illustrator/inkscape

e quindi lo vorrei editabile...

https://hub.qgis.org/issues/3975
Ho provato ed ho seguito le istruzioni del bug qui sopra ed in effetti 
funziona...
Ovvero se nell' "advance Placement Setting" - Sistema di Posizionamento 
Automatico

https://www.youtube.com/watch?v=w2j-o8XhoI4=em-upload_owner
untaggo la voce "raccomandata" disegna testo come contorno, allora 
quando lo esporto

in SVG riesco ad editare il testo... (non funziona come pdf)


Ci sono degli aggiornamenti su questo bug ?

Grazie

Hi,

Buffer require some parameter since you can choose the "style" of buffer. You 
have some example on PostGis documentation (parameters are the same)
http://postgis.net/docs/ST_Buffer.html

QGis define this parameters in Settings->Options->Digitizing->Curve offset tool.

You can get this parameters via QSettings :
join = QSettings().value("Qgis/digitizing/offset_join_style", 0, type=int)
quad = QSettings().value("Qgis/digitizing/offset_quad_seg", 8, type=int)
endCap = quad

Hi everyone,

I would like to find more details about QgsGeometry::buffer with more styles.

In QGIS API Documentation there are two version of the buffer:
Simple version with distance and segments and with sytles.

The one with styles is defines as: ( distance, segments, endCapStyle, 
joinStyle, mitreLimit );

I do not understand the followings parameters:

endCapStyle: Round (1) / Flat (2) / Square (3) end cap style
joinStyle: Round (1) / Mitre (2) / Bevel (3) join style
mitreLimit: Limit on the mitre ratio used for very sharp corners

Does someone has some examples or recommend a book where to find more details 
please?
The QGIS API Documentation does not give me too much.

[Qgis-user] Attribute table error in QGIS 2.15.0-Master

[Gustavo Martínez Puljak]

Hi,

I am using QGIS 2.15.0-Master in a 64bit Linux system. When I open the
atribute table for a layer (postgis or shape) all the columns repeat the
data of the first column (including the name of the column). The number
of columns is correct. The data is correctly shown in form view, but not
in the tabular view.

Thanks in advance.

Agreed, don't start field names with numbers.

Re: [Qgis-user] SQL display expression

[Neumann, Andreas]

Hi Christoph, 

Are you talking about the left column in the forms view? 

What do you mean by "not related"? Do you mean related, but not
contained in the same table? 

Is this for a value list lookup? 

For a 1:1 relation? 

QGIS expressions don't know "SELECT". The expression always works on a
single feature. It can't return records.  

There could be several ways to do what you want: 

1. use joins (layer properties --> joins) 

2. use the attribute(getFeature()) expression 

3. Create a virtual layer (starting from version 2.14) --> see
https://docs.qgis.org/testing/en/docs/user_manual/working_with_vector/virtual_layers.html


I hope that one of the above ways help you solve your problem. 

Greetings, 

Andreas

[Qgis-user] Shapefiles with all numeric attribute names don't classify right?

[Ian Turton]

I have a shapefile with a bunch of attributes called 1980,1990,2000, etc to
represent the years the data is for. They are integers (if that matters)
but when I try to use them in a Qgis (2.14.2-Essen) the styler recognises
them as numeric but when I try to produce a graduated style all the classes
are  set to -2147483648 - -2147483648. If I rename the attribute to
1980_inc or inc1980 the classifier is happy and everything works as I
expect.

Does anyone know what might be going on?

[Qgis-user] SQL display expression

[Christoph Lauber]

Hi

 

I have a question about the display expression for forms.  The aim is to
show data of a table that is not related by QGIS.

 

What I would like to do is to write a SQL to my SpatiaLite database to fetch
some data. I suppose, that the display expression is restricted to the
“select column” clause like: “"pkuid"   ||  ' '  || CASE WHEN art = 1 THEN
'this' ELSE 'that' END”. When I put a select clause in it like “CASE WHEN
"art" THEN (SELECT value FROM WI_D_Inventar_Art WHERE id = "art") ELSE
'Undefined' END” I get an expression is invalid error (the expression works
in spatialite_gui). It seems that the SELECT keyword is not accepted.

 

Is there any possibility to write “free” SQL-Syntax for the display
expression?

 

I wrote already a function that connects to the database, fetchs the data
and closes the database. It works, but it is slow.

 

Thanks for your help.

 

Freundliche Grüsse

Christoph Lauber

Salve a tutti,
stamane mi sono accorto che creando un campo Int o Real per l'elevazione (no
Integer64) tutto procede bene, ma alla successiva apertura dello shape mi
ritrovo i campi in formato Integer64.
Questo crea parecchi problemi come per esempio non è possibile usare il
plugin Interpolazione, in quanto non ammette campi Integer64.

da una ricerca ho trovato questo bug [0], si tratta dello stesso problema o
bisogna aprire altro ticket?

Re: [Qgis-user] QGIS project with no projection

[Andrew Harfoot]

QGIS is configured into a non-earth or local CRS mode by doing the 
following (in 2.14):


1. Turn off 'On the Fly CRS transformation' (Project > Project 
Properties > CRS)
2. Ensure that the measurement ellipsoid is set to 'None / Planimetric' 
(Project > Project Properties > General)
3. Set the coordinate, distance and area units to 'Map Units' (Project > 
Project Properties > General)


All of these can also be set in the application level settings as the 
defaults. QGIS can also be prevented from prompting for a CRS when 
loading data that does not have one (QGIS still assigns a CRS, but 
essentially it is ignored, so this isn't quite what Simon was asking 
for, but close)


The LocalCoordinateSystemSetter in FME creates custom CRS for features 
passing through it, optimising them for equal area or distance. The same 
customised CRS could be implemented in QGIS, what is missing is a tool / 
plugin that would automatically generate them.


Cheers,

Andy

Why doesn't QGIS have a generic Coordinate System for X/Y in meters 
(and maybe one in feet for the less developed nations ;-) )? It would 
be particularly useful for non-geographical datasets and would open 
QGIS up to being used more readily in other fields.


Similarly, it could have generic projections for equal area and equal 
distance calculations too. I know these are all possible because FME 
has all these features.

After all, there's no reason spatial data has to be GEOspatial data.

Simon,

You *must* specify a projection, but within some limits, the
projection doesn't matter. Basically, if the GeoTIFF uses units of
meters and you want your distances in meters, you can load the
GeoTIFF in *any* projected CRS that uses meters. An example would
be to use any of the UTM zones. You cannot use a lat-long CRS such
as the default WGS 84, because QGIS will convert (naively, *not*
using great circle distances) from decimal degrees to meters.

Once the layer is loaded, all geometry calculations are done in a
Cartesian plane.

I answered a similar question on GIS.SE  regarding
someone who wanted to use QGIS to map indoor location data.

Hi Simon,
If you know the real-world width and height of the area
covered on the image, could you not geo-reference it to have
lower-left at 0,0, and then the top-right at the applicable
location in the projection of your choice, and then work from
there?

The problem is picking an applicable projection. I can't see
any generic "X,Y" projection, let alone one that is suited to
equal-area or equal-distance in the projections list. They may
exist, I'm just failing to find them. They all seem to assume
they're "somewhere" in the world (which can be a problem if
the data is spatial but not geographical).
Personally if it's a relatively small area (a few km across),
I'd probably just use a standard Mercator for the applicable
part of the world probably.

I want to use QGIS to make measurements such as distances

QGIS seems to require that I choose a projection. What
would be the best
choice for my needs? Can I make a custom projection with
no ellipsoid or

If I import my geotiff and don't specify a projection QGIS
assumes my units
are in degrees rather than metres, which will make
measurement of distances
and angles inaccurate.

Grateful for assistance.

Upon further investigation I found out the problem arises from the
number of significant digits of the nodes.

The node pre-existing in the layer has coordinates:

POINT(9.9145925045 45.6483308807)

The connected node in the newly created line has coordinates:

POINT(9.9145925 45.64833088)

Why is that? If I snap a node in an existing node, shouldn't the same
coordinates be used?

Do you have libproj.so? If so, you can make a link to that file, e.g.:

Re: [Qgis-user] Crayfish plugin OSError: libproj.so.0

[Werner Macho]

Hi,

That error:
OSError: libproj.so.0: cannot open shared object file: No such file or directory
looks a bit suspicious to me .. Are you sure the package libproj0 is installed?

regards
Werner

[Qgis-user] Crayfish plugin OSError: libproj.so.0

[Alexandre Neto]

I'm having troubles loading the Crayfish plugin in ubuntu 15.10 wily. No
problem whatsoever with windows tho.

Couldn't load plugin crayfish due to an error when calling its initGui()
method

OSError: libproj.so.0: cannot open shared object file: No such file or
directory

Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/qgis/utils.py", line 335, in

line 73, in initGui

[Qgis-user] Connect lines in Geoserver

[emmexx]

I was trying to update a lines layer from geoserver (WFS) to add a new
line and to connect it to other lines.
I remember I did that in the past but I'm not sure now.

I enable snapping, create the line, add the points and snap the starting
and ending nodes to other lines, then I save.
If I try to move the connecting node in qgis, both lines move.
But when I check on geoserver the 2 lines are not connected (I use that
layer for routing). I exported the layer data to josm and even there I
see that the lines are not connected.

What am I doing wrong?

Thank you
maxx
